<DIV><FONT face=Arial>Dear RB</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>OK.... as discouraging as the facts may be, the facts are
reality, and they must be dealt with to avoid future problems.</FONT></DIV>
<DIV><FONT face=Arial>1: Can different species be grown, that have higher Mean
Annual Increments of growth?</FONT></DIV>
<DIV><FONT face=Arial>2: Can the woodlots be managed better?</FONT></DIV>
<DIV><FONT face=Arial>3: Can cooking practises be changed?</FONT></DIV>
<DIV><FONT face=Arial>4: Would more efficient stoves help
significantly?</FONT></DIV>
<DIV><FONT face=Arial>5: Can other forms of fuel, or other sources of
energy, be used to take some of the pressure off the woodlots?</FONT></DIV>
<DIV><FONT face=Arial>6: Would some form of "Agroforestry" be possible, to put
the land to a higher use, with multi-cropping?</FONT></DIV>
<DIV><FONT face=Arial>...etc...</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Most people like to do things the way they have always
been done. They can't expect different results if they do things the same way
they have always done things in the past. The cruel facts are that if they want
different results, then they will have to find changes that are acceptable to
them, OR choose to live with the consequences of their present practises. Those
seem to be the cruel realities.</FONT></DIV>

if the land is totally dedicated to tree growth and fire wood production is
about 20 tons per hectare per year. </DIV>
<DIV> </DIV>
<DIV>Our Maasai women use about two tons of wood a year each, and that is with
a pretty good stove. before our stove they were using 5 tons per year
for each house. </DIV>
<DIV> </DIV>
<DIV>so on a hectare of dedicated wood growing land, we could grow the wood
for 10 houses.</DIV>
<DIV> </DIV>
<DIV>this may seem discouraging. not many rural areas can afford to set
aside tree growing space like this. I know the Maasai can't.

<DIV><BR></DIV>
<DIV dir=ltr>Hi All,
<DIV><BR></DIV>
<DIV>Would anybody be able to clarify from an emissions standpoint, (and
honestly I am not sure I understand it completely) is wood smoke is 'food'
for tree's?</DIV>
<DIV> </DIV>
<DIV><FONT face=Arial># The first thing to do is define "smoke". :-) While
"pyrolysis products" may be beneficial for seed treatment or insect control,
I am guessing that the quantity, distribution and lack of permanence of
"pyrolysis products distributed as a result of poor combustion" would likely
have a minimil beneficial or detrimental effect on plant
growth.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial># The "products of complete combustion" of biomass are
basically CO2 and water vapour. Additional CO2 in the atmosphere will be
beneficial to plant growth only if existing CO2 levels were the constraint
to plant growth. I am guessing that this is seldom the case... the limiting
factors are probably more likely to be Sunlight, Moisture, and
Nutrients.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV> If so, take my small stove business - if I sell 100 stoves in a
month that in total will use say - 1 ton of biomass (charcoal so perhaps 7
tons of wood). How many tree's would myself and my customers need to plant
every month to not only achieve a positive feedback loop of increased
biomass but be able to 100% reduce the emissions produced? </DIV>
<DIV> </DIV>
<DIV><FONT face=Arial># The number of trees you need to support a stove
depends on the "Mean Annual Increment of Growth" for the trees being used
for fuel. For example, if heating my home requires 5 cords of wood per year,
and the "Mean annual increment" for spruce trees is 1 cord per acre per
year, then I would need an area of 5 acres to grow the trees required to
heat my home with no net increase or decrease of the wood on my woodlot. If
the woodlot is managed in a sustainable manner, then it is unlikely that
"re-planting" will be required, in that the trees will naturally "re-seed"
the harvested areas, or, depending on the species, the trees will send up
clones from their roots. Note that if one is not using "Sustainable
Management Practises, there will never be a gain in wood availability, no
matter how many trees are planted.</FONT></DIV>
<DIV><BR></DIV>
<DIV>Is this even possible? I feel very strongly that woodfuel stove
manufacturers and users should be responsible for replanting, growing and
advocating tree planting as a future source of renewable energy, if only for
our own job security. I am also very interested in finding out how one can
actually measure the number of tree's needed to be grown compared to the
number of stoves in use? (especially if the woodlot is managed under a
pruning/coppicing regime).</DIV>
<DIV> </DIV>
<DIV><FONT face=Arial># It is not that difficult. You need to know the
amount of wood consumed per year per stove, and the "Mean Annual Increment"
of growth for the tree species being grown in the particular area, and the
percentage of the "Mean Annual Increment" (MAI) that actually gets
used as fuel. For example, if the MAI is 1 cord per acre per year, and if
half the wood is sold off as logs, then 2 acres would be required to yield 1
cord of fuel wood.</FONT></DIV>
<DIV><BR></DIV>
<DIV>many thanks for any thoughts, </DIV>
<DIV> </DIV>
<DIV><FONT face=Arial># I hope this is helpful.</FONT></DIV>

other.<BR><BR>Is it possible that here are more TLUD's burning char (high

that was the case,<BR>right?<BR><BR>I know there are reasons provided for
making and saving the char and a whole<BR>enthusiast sector devoted to the
matter, however it would be unfortunate if<BR>the acronym TLUD was tied to
only one form of combustion, while the world<BR>merrily went ahead with
two.<BR><BR>What are your thoughts on this?<BR><BR>Thanks<BR><SPAN
